This example demonstrates VizHub’s support for modular JavaScript and external libraries. It imports the D3.js `select` function via UNPKG and a local ES6 module, `myMessage.js`, to display a message. The page fetches a CSV file from a GitHub gist, though the file’s content is not rendered. The `styles.css` file styles the message with large, centered text, showcasing CSS loading and parsing within the VizHub environment.
